High-precision C purlin roll former

With its superior technological advantages, the C-shaped roll forming machine has become a core piece of equipment in the steel structure building materials production industry. Its high performance directly boosts both production efficiency and product quality, creating a significant competitive advantage for building materials processing companies.

The core strength of this equipment is its efficient and continuous production. Utilizing an advanced cold roll forming process, it eliminates the need for preheating the metal sheets. 15-25 sets of precisely aligned rolls achieve continuous rolling and shaping, achieving processing speeds of 10-30 meters per minute. Maximum production capacity in a single 8-hour shift reaches 15,000 meters, representing production efficiency 5-8 times that of traditional welding processes. This high efficiency not only easily meets the mass production needs of large-scale orders but also significantly shortens delivery cycles, enabling companies to quickly respond to market changes.

The forming accuracy is industry-leading. The precision-ground roll die, coupled with a high-precision feed system controlled by a servo motor, ensures that the cross-sectional dimensional tolerance of the C-shaped purlins is strictly controlled within ±0.5mm, and the straightness error does not exceed 1mm/m. This high precision ensures that the purlins require no secondary processing during building installation and can be directly bolted to the main steel structure, significantly reducing on-site construction costs and improving installation efficiency.

Material utilization exceeds 95%, far exceeding traditional processing methods. The continuous rolling process fundamentally eliminates the shear waste generated by traditional stamping. Actual measurements show that each 10,000 meters of purlins produced saves approximately 1.2 tons of steel. Based on an annual production capacity of 1 million meters, this translates to an annual material cost savings of over 100,000 yuan. Furthermore, the cold-bending process fully preserves the steel's original mechanical properties, resulting in a 15%-20% increase in compressive strength compared to hot-rolled steel. This ensures material economy while enhancing structural safety.

The system boasts significantly higher operational flexibility and intelligent capabilities. Using a PLC touchscreen control system, operators can quickly set parameters such as purlin length and thickness. Changing molds takes only 30-60 minutes, allowing flexible production of C-shaped parts with widths ranging from 80-300mm and thicknesses from 0.8-3mm. This system perfectly meets the diverse needs of buildings with spans of 6-15 meters, such as small and medium-sized factories and warehouses. The equipment's built-in intelligent fault diagnosis system monitors the operating status of the rolls and plate feed deviation in real time. If an anomaly occurs, the machine will automatically shut down and issue an alarm, minimizing manual intervention costs and the risk of equipment damage.

Energy consumption and maintenance costs are also significantly improved. Compared to traditional hot rolling processes, cold roll forming reduces energy consumption by over 60%, significantly reducing energy consumption during the production process. The key roll components, made of high-strength alloy steel with a hardness of HRC55 or higher, have a service life of over 500,000 meters. Annual maintenance costs are less than 3% of the total equipment price, significantly reducing long-term operating costs. The C-shaped purlins it produces have a compact cross-sectional design and light weight, which can effectively reduce the overall load of the building, help meet green building standards, and become key equipment for building materials companies to reduce costs, increase efficiency, and expand market share.
